The purpose of the different modules wasn’t clearly defined, which lead to inconsistent responsibilities between the different modules. Define each module’s purpose and move a few files between modules to satisfy these definitions. There are a few more larger changes that will need to be made for a fully consistent module structure. These are FIXMEs in the new Modules.md document and I’ll address them in follow-up PRs.
